Meltblown non-woven fabric production process

Melt-blown non-woven fabric is a special technology non-woven fabric formed by polymer feeding---melt extrusion---fiber formation---fiber cooling---web formation---reinforcement into fabric. The woven fabric is comfortable, soft and good in hand, and can directly touch the skin. The advantages of fine fibers, small pores and small pores, and good solid barrier properties. The uniformity of environmental protection and hygiene is good. Advantages such as hydrophobic and lipophilic. It is a kind of non-woven fabric with good sales in the market.


Since the beginning of the 21st century, the international meltblown non-woven fabric technology has developed by leaps and bounds. Non-woven fabrics are very useful.


American Mountain Company and Connaught Company have successfully developed two-component meltblown technology earlier, including skin-core, side-by-side, triangular, etc., usually the fiber size is close to 2μ, and the number of holes in the meltblown spinning component can reach With 100 holes per inch, the extrusion volume per hole can reach 0.5g/min.


Skin-core type: It can make the non-woven fabric feel soft, and can be made into concentric, eccentric, and special-shaped products. Generally, cheap materials are used as the core, and the expensive polymer with special or required properties is the outer skin layer. For example, the core is polypropylene and the outer skin is nylon to make the fiber hygroscopic; the core is polypropylene, and the outer skin is a low adhesive layer. Melting point polyethylene or modified polypropylene, modified polyester, etc. For carbon black conductive fibers, the conductive core is wrapped inside.
